TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY G. CADY, of the city and county of St Louis,and State of Missouri, have invented certain new and useful Improvementsin Valve-Seats; andI'I do hereby declare that the following is :1. full,clear, and exact description of the sume, reference being hed to theaccompanying drawing, and to thc letters of referencemnrked thereon, asforming a, part of this specification.

To enable others skilled in Qthe art to make and use my invention, Iwillproceed to describe its construction.

In the annexed drawing, H represents a. metal cylinder which is providedwith a. shoulder on the inside und top to receive the valve andvalve-sent. Seid valve ltud valve-sent may be made of either leather orrubber. Il take a suitable piece of either of' the aforesaid muterinls,und so shepe it es to t tight n the cylinder and against the shoulder ofthe sume. It is particularly desirable thatvt should fit so tightly inand around the inner circumference of cylinder H as to eectually prevent-water from escaping between it and the cylinder. The edge of thisvulve-seat B should also project over the shoulder, so es to render itplinblennd elastic to the valve above. I now take a. second piece ofrubber or leather, and likewise shape it to fit in the cylinder H and cntop ,of valve-seat B. In the centre of this piece of. leather or rubberI cut a. ring, leaving, however, the inside portion suspended orconnected by a. narrow strip to the mein piece. This inside piece,represented by F, should fit accurately over the valve-seat, es shown inthe drawing. represents a weight, which is attached to the flexible ringby means of a screw passing up through its centre.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

A valve, constructed of the cylinder` H, bevelled pecking or seat B,exible ring F, with its Weighted tongue A, ell arranged substantially asshown and described.
